Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612082, here are decompositions:

3 + 31612079 = 31612082
13 + 31612069 = 31612082
199 + 31611883 = 31612082
241 + 31611841 = 31612082
349 + 31611733 = 31612082
373 + 31611709 = 31612082
379 + 31611703 = 31612082
409 + 31611673 = 31612082

Showing the first eight; more decompositions exist.
